I'm looking for suggestions on the best power tool or blade to flush cut my subfloor to the wall, ensuring I don't accidentally cut into the joists. I've tried using an oscillating tool, but it's taking way too long even with a new Diablo blade. I need a clean cut flush with the wall studs to install a new piece of plywood. Any advice?

An oscillating tool can work if you have the right blade! Look for aggressive teeth on your blade and use it at a 45-degree angle. Just be prepared to replace the blades often, as they do wear out fast when cutting through subfloor material. If you want to avoid that hassle, a toe-kick saw or a powered jamb saw would make a cleaner and easier cut.
A circular saw set to cut just a bit short of flush can also do the trick, especially if you don’t need it to be perfectly even. Although, if you're looking for perfection, the toe-kick saw really is your best bet. Just be careful with it since it's known for having a kickback.
You might want to consider using a toe-kick saw. It's designed for this kind of job and can cut right up against the wall without damaging the joists. I used a toe-kick saw when I was removing subfloors that went underneath the trim and it worked quite well. Just a heads up, it can be a bit tricky to handle, so make sure you’re careful with it!
I’ve heard they can be quite dangerous. Did you have any issues with kickback?
I’m leaning towards the toe-kick saw, even though I’m not sure how much use I’ll get out of it after this!
